Abstract: A vehicle roof cleaner is provided with a pair of vertical supports, an upper cross bar, a cleaner assembly, and an adjustment mechanism. The upper crossbar connects the pair of vertical supports, and the cleaner assembly is movable along the pair of vertical supports and positionable below the upper crossbar by the height adjustment mechanism. The height adjustment mechanism includes a load bearing mechanism, a spring load assembly, and an activation mechanism.

Abstract: A single stage two plane coiled reinforcing bar stock straightener adapted to straighten an infeed of coiled reinforcing bar in both the horizontal and vertical planes for providing the straightened delivery of coil fed reinforcing bar material to processing and converting machinery.

Abstract: An endless belt conveyor provided with a tensioning mechanism which includes an idler in operative contact with the return run, the idler being supported by a movable carriage. Tension adjusting means are provided which may move the carriage and idler in either a first direction to increase the tension on the endless belt or in a second direction to reduce the tension for purposes of resplicing the belt. The tensioning mechanism further includes control means which senses the tension on the return run and which may initiate movement of the carriage in either direction. The means for sensing the tension includes a normally open limit switch which is adapted to close when the tension on the return run falls below a predetermined value.
